I mean, no matter how hard ALL of us try, no one is going to ever have the perfect art style. each of us have different and unique styles, so honestly? dont compare yourself to other artists. If you're happy with your art style, then keep doing it! If you feel you would like to improve, then go right ahead :]
also heres that video: https://youtu.be/COTBfT6N6-M
honestly, it helped me a lot when i just kinda felt like my art style wasn't..the best. after watching this vid, i kept experimenting and testing out new things that fit, leading up to my art style now. So i def recommend this video if you see room for improvement.
